This invention relates to improvements in talking machines and moreparticularly to talking machines of the kind which are adapted forcontinuous sound reproduction, whether by playing 5 a succession ofrecords automatically furnished for example from a magazine or by therepeated playing of the same record.

Among the objects of the invention are to provide a machine in which thesound box may be lifted, lowered and swung outwards by a member drivenintermittently from the motor of the machine, the extent of the swingingmovements being variable both automatically and manually.

A further objector the invention is to provide a machine which isadapted for use either as a magazine machine in which a number ofrecords contained in a magazinecan automatically be moved in successioninto the playing position, played and automatically removed, or as arepeater machine to repeat the playing of a single record as o ften asdesired.

A further object of the invention is to pro-.-

vide a machine which may be used either as a magazine machine, arepeating machine or an ordinary machine manually operated.

A further object of the invention is to provide a machine in which thechange-over from oneform of operation to another-may be effected at willbythe manipulation of a suitable control.

A further object of the invention is to provide an automatic magazinemachine with which records of different sizes may be played. v Accordingto the invention, a machine kind referred to is provided in which thesound box lifting, lowering and swinging means adapt-.

ed to be driven intermittently from the motor of the machine co-operateson the one hand with a sound box lifting and lowering lever and on theother hand with a sound box swinging lever.

swinging mechanism movements of different ex-.

tent, periodicity or rapidity.

. The movement of the intermittently drivenmember into alternativepositions may also serve to connect or disconnectsaid member with or Themember driven intermittently by the motor may be in the form of areciprocable plate.

from means for feeding a new record to the machine.

The means for moving the sound arm outwards. may be in the form of aswinging lever operated by the member intermittently driven from themotor and auxiliary means may be provided to co-operate with the leverto move the sound arm outwards through distances corresponding to thediameter of the record to be played. These auxiliary means may be causedto occupy a plurality of positions according to the size of the recordto be played and the positioning of said auxiliary means may be eifectedeither manually or automatically by a record in the course of thetransfer of said record from the magazine to the turntable.

During magazine operation the sound arm is moved outwards, beforeplaying is commenced, to a point beyond the edge of the largest recordand means are provided to subsequently move said sound arm inwards to apoint over the commencement of a record, said means being adapted torelease the sound arm at an appropriate point corresponding to the sizeof the record to be played. The release of the sound arm at theappropriate point=may be effected bythe auxiliary sound arm positioningmeans referred to above.

During magazineoperation, whenthe magazine is emptied andthe last playedrecord is removed from the turntable the sound arm is permitted to fallto a position below the playing position in whichposition it operates aswitch to open the of the motor circuit and thereby stop the machine.'The intermittently driven member is driven from the motor through aclutch device which is put in either by-hand to start the machine orautomatically during playing when the end of a record is reached by therocking of a detent memher. This detent, .when operated manually to istart the machine, closes a switch arranged in shunt with the switchpreviously referred to, so that the machine, can be'started even whenthe sound arm is in its lowest position.

Means are provided to prevent the clutch from being put in when themachine is set to operate as an ordinary machine even when the detent isrocked and in this case the movement of the detent when playing of arecord is finished may be utilized to operate an automatic stoppingdevice which during magazine and repeater operation remains inoperative-The record transferring mechanism is prefer-' ably of the kind in whichthe records are moved fromthe magazine in which they are arranged in apile, by a horizontally swinging arm carrying n lock the control memberagainst movement during the automatic cycle.

The invention is illustrated in the accompanying drawings in which Fig.1 is a plan view of the compiete automatic apparatus, the turntable andsound arm being shown in dotted lines for the sake of clearness, theparts being shown in the position for automatic magazine operation, withthe record trans ferring device in the position for engaging a record inthe magazine.

record engaging and releasing means such as is i Fig. 24 is a diagram ofthe electric wiring of the machine.

Referring to the drawings, the machine is mounted in a cabinet 1(Fig. 1) divided into two main compartments 2 and 3, the compartment 2containing the whole of the mechanism for raising, swinging and loweringthe sound arm, for removing a record and for operating the maga-. zinemember which brings a new record to the turntable. This mechanism ismounted by means of base plate 4 upon a motor board 5, while thecompartment 3 serves as a receptacle for played records.

At the right hand side of the machine is a control lever '74 pivoted at75 and having a roller '74 co-operating with a spring influenced notchbar 167 pivoted at 167, so that lever 74 can be set for magazineoperation (Fig. 1), repeater operation (Fig. 2, full lines) or ordinaryoperation (Fig. 2, dotted lines).

An electric motor 180 (Fig. 22) furnished with the usual governor 181and furnished with cur-. rent through switches described later, drives avertical shaft 13, carrying the turntable 90. A toothed wheel 22 (Fig.6) is fixedly mounted on the shaft 13, and with it is adapted to engagea tooth 21 on an arc-shaped clutch lever 17 pivotally mounted by meansof a pin 29 on a clutch plate freely mounted on the shaft 13. The meansfor operating this clutch for initial starting of the automaticmechanism consist of a push rod 163 with button 162, mounted to movehorizontally on guide pins 163 on the plate 4, against a pressurespring, and to rock the arm 24 of a lever pivoted at 24' against theaction of a spring 25 anchored to the base plate 4 and push the end 23of the lever out of engagement with the end 18 of the clutch lever 1'7,so that a spring 19 attached at one end to part 18 and at the other endto stud 20 on plate 15 turns the clutch lever 17 about its pivot 29, andengages tooth 21 with the toothed wheel 22, whereby the plate 15 isdriven and will continue to rotate until, on the cycle of automaticoperations being completed the clutch is disengaged by the arm 24 whichhas been moved by its spring 25 to engage again the end of lever '17.The clutch is out during the playing of a record and after a record hasbeen played, the clutch is again engaged, but this time automaticallythrough means (described below) thrown into operation by a reversemovement given to the sound arm after playing a record.

On the underside of plate 15 is carried a gear wheel 14 (Figs. 6 and 22)engaging with a larger gear wheel 16 which drives a shaft 12 journalledin the base plate 4. Mounted on the shaft 12 are the various cams whichoperate the several elements of the machine that furnish the records tothe turntable, lift the sound box at the end of a record, and repositionit for replaying a record or playing a new one, and remove a record fromthe turntable.

The eccentric cam 11 (Fig. 23) lying immediately beneath the gear wheel16 co-operates with a cam ring 9 having anti-friction rollers 10 whichlie upon the periphery 'of cam 11, and an arm 7 extending from the ring9 is pivoted at 8 upon one end of a flat plate 6 (Figs. 1-4, and

13-1'7) adapted to slide horizontally on a ball "towards the right inFigs. 1 and 13-16).

It is the reciprocation of this plate 6 which causes the lifting of thesound box and sound arm, the horizontal movement of the sound arm totake a new position, the lowering of the sound box onto the record, andalso the movement of the record conveyor to and fro between the magazineand the turntable.

The means for lifting the sound arm and sound box and lowering same willnow be described. Upon the upper surface of the reciprocating plate 6(Figs. 12-17) is pivotally mounted at 66 a shaped and slotted plate 41.A light spring 67 anchored on plate 6 presses plate 41 against stop 47.The forward end 42 of plate 41 is bevelled off downwards towards theplate 6.

This bevelled end 42 co-operates with a roller 43 mounted in a slot in alever 44 (Fig. 12 and in dotted lines in Figs. 13-16) which will betermed the sound arm lifting lever. This lever 44 is mounted to rockabout a horizontal axis, being mounted at one end between studs 45carried on the base plate 4, and is lifted by the bevelled end 42 ofmember 41 passing under the roller 43, as the reciprocating plate 6 ismoved The free end 46 of the sound arm lifting lever 44 is flared andprojects beneath a stud or post 47 (Fig. 12) carried on an arm 48extending from a collar 54 surrounding the lower thickened end 51 of thevertical elbow portion of the sound arm 27 (see also Figs. 10 and 11).The collar 54 and sound arm 27 have common pivots 49' (Fig. 11) and alimited play is allowed between the collar and sound arm by means of abolt 57, mounted on the collar 54, and nuts 59 which engage with a ring58 secured on the sound arm. When the sound arm lifting lever 44 isrocked vertically, the post 47 is lifted and the radial arm 48 and soundarm 27 are rocked about their pivots 49 (Figs. 11 and 12) into theposition shown in dotted lines in Fig. 12, to raise the sound box 50above the playing position. The pivots 49 pass through the thickened end51 of the sound arm, and through a short tubular member 52 shaped asshown in Fig. 11 to form a ball joint. This tubular member 52 forms afurther extension of the sound arm 27 and is itself mounted to rotate inball bearings 53. The axis ofthe ball bearing is at a small angle (ofthe order of 2) to the vertical in the direction which tends to causethe sound arm 27 and sound box to'swing by gravity towards the centre ofthe record for a purpose explained below.

A coiled spring 55 is provided on one of the pivot pins 49, one endbeing connected with the collar 54' and the other end to a tensioningnut 56 on the pin 49, so that the outer end of the arm 48 is gentlyurged downwards away from the sound arm 27. The arrangement is such thatthe sound arm is capable of a limited vertical movement, to permit theneedle to accommodate itself during playing to any irregularities in thelevel of a record, without affecting the position of the collar 54 andarm 48, and furthermore when there is no record on the turntable thesound box is permitted to drop slightly below the playing position for apurpose to be described later.

' The sound arm lifting and lowering mechanism has of course to beoperated when a record has been played, whether the machine is workingas a magazine machine or as a repeating machine.

In the case of the mechanism being set for vmagazine operation, when theroller 43 has mounted the bevelled end of plate; 41, and lifted thelever 44 and the sound arm 27, it travels along again that a record isbrought from the maga-- zinc and placed on the turntable and sound armis swung outwards.

If, however, the machine is set to operate as a repeater, a lesserinterval is required between the raising and lowering of the sound arm,and the path of travel of plate 6 is modified to produce the desiredeffect. When the control lever 74 and the guide roller 40 carriedthereby is moved from the magazine position shown in Fig. 1 to'the"repeater position shown infull lines in Fig. 2. the path of the plate 6and slotted plate 41 mounted thereon is so varied that the roller 43 onthe sound arm lifting lever 44, after riding up the wedge-shaped end ofthe plate 41 (see Fig. 15) shortly thereafter runs down a rearwardlyinclined surface 61 on the plate 41 (Fig. 16). The raising and loweringmovementsof the sound arm 2'7 in this case succeed one another with ashort interval and both take place during movement of the reciprocatingplate 6 in one direction, i. e. towards the right in Figs. 15 and 16.

In order however that, during frepeater" operation no lifting of thesound arm 27 shall take place during the return movement of thereciprocating plate 6 the incline 61 during this return movement isbrought out of the path of the roller 43, by movement of the plate 41about pivot 66. This movement is effected as follows: A headed pin orplunger 62 (Fig. 12), is carried loosely in an aperture in the sound armlifting lever 44, and kept down by a light spring 62' anchored at 62" onlever 44, so that the end of the plunger projects below the underside oflever 44. 'When the lever 44 is lifted as above described to raise thesound arm, the plate 41, as it moves to the right, passes freely beneaththe plunger 62. When the lever 44 drops owing to roller 43 passing downincline 61, the lower end of the plunger comes to rest upon the surface63 of plate 41 and it remains there until on further movementof plate 41towards the right the plunger drops into the space 64, as shown in Fig.16. During the return movement of plate 6 the plunger 62 will thenengage the cam surface 65 on one side of space 64 and the lever 41 willthus be moved about its pivot'66 against the action of spring 67, intothe position shown in Fig. 17 out of the path of roller 43 so that thereturn movement of plate 6 towards the left does not cause the sound armto be lifted. The spring 67 returns the lever 41 to its normal positionagainst stop 41' when the latter is released by the plunger 62 movingout of the slot 64.

The means for swinging the sound arm back to the starting position afterthe playing of a record will now be described. The sound arm 27 afterbeing lifted from the record when playing is completed, is swungoutwardly by means of a lever 68 (Fig. 3) pivotedat one endon a verticalpin 69 in the base plate 4, and having at a point intermediate itslength a downwardly depending pin 70 which engages in a slot 71 in Theslot '71 in the plate 6 is of substantially "i shape and the sound armswinging lever 68 is only moved by the plate 6 when the pin on saidlever is in the limb '22 of the slot, Figs. 3 and 4), the movementceasing when the pin 70 moves into the limb '73.

When the machine is operating as a magazine machine it is necessary thatthe sound arm 27 shall always move outwards a greater distance than whenthe machine is in repeater operation, so that the sound arm may be clearof the new record being brought to the turntable.

The extent of movement of the lever 68, which determines the extent ofmovement of the sound arm 27, depends upon the path of travel of thereciprocating plate 6 for on this depends the time during which the pin70 remains in what may be termed the active limb 72 of the slot '21.

For magazine operation therefore the path through which thereciprocating plate 6 moves is one which ensures that the pin '70 willtraverse practically the whole length of the active limb '72 of the slot'71 before entering the other limb '73.

In Fig. 3 is shown in dotted lines the position I of the arm 68 beforebeing moved towards the right by the movement of plate 6. It will beobserved that in this position the pin '70 is near to the bottom of part'72 of the shaped slot and in this position it remains stationary untilas plate 6 moves to the right the pin '70 is engaged by the left handedge of part 72 of the slot and the lever 68 is thereby swung in aclockwise direction until the pin '10 enters the part '73 of j; theslot, when movement of the lever 68 and therefore outward movement ofthe sound arm 2'? ceases. The extent of movement of said pin 70 in theshaped slot is in this case a maximum and the sound arm is thereforeswung outward for the maximum distance.

In the case of repeater operation however the sound arm 27 is requiredto be moved. outwards only through a distance which will enable thestylus to be lowered directly on to the edge of the record still on theturntable.

The reciprocating plate 6 therefore, as "previously described inconnection with the raising and 74 in position for repeater operation,the pin '20 has a less distance to travel to reach the part '73 of slot'71 and bring the arm 68 fromthe full line position to the dottedposition than is the case in Fig. 3.'

But while the sound arm is swung outwards a lesser distance for repeateroperation and a greater distance for magazine operation, it is alsonecessary to provide for the needle descending (whether-during repeateror magazine operation) in different positions for 10 and 12 inchrecords. For repeater operation the position at which the needle dropsdepends on whether the radial arm 48 from the sound arm elbow is pushedoutwards by engaging with the end of lever 68, or with a member 138mounted movably thereon. For magazine operation, the position at whichthe needle drops depends, not upon the extent to which the arm 48 ispushed outwards but upon the extent to which it is subsequently pulledinwards again.

The mechanism determining these movements is as follows: A lever 129(Fig. 3) mounted to rock vertically about a pin 195 carried on the baseplate (see Fig. 18) has its free end normally urged upwards by a spring130 arranged between the lever and the base plate 4 and a. headed pin187 secured to the base plate 4 and passing through an aperture in lever129 limits the upward movement of the latter. The lever 129 has atitsleft hand end an upturned edge 135, inclined and having a fiat 135'at its highest part. A horizontally rocking lever 132 mounted at 133 onthe base plate 4 (Fig. 1) is moved either into the position shown infull lines or into that shown in dotted lines by the passage of a 10 or12" record from the magazine, and the roller 134 on the end of saidrocking lever either occupies a position on a flat 135' at the upper endof an inclined surface 135 of lever 129 and there depresses the lever129, or has been dislodged from the flat and pushed down the incline bythe lever 129 rising. The manner in which the size of the record passingfrom the magazine to the turntable determines the position of lever 132will be described later in connection with the magazine itself.

Carried on the end of the radial arm 48 is an upstanding post 131 (Fig.10) and this is as will be seen from Fig. 1 adapted to be engaged eitherby the lever 68 itself or by a T-shaped member 138 pivotally mounted at138 on said lever 68. The post 131 is of such height that it lies in thepath of lever 68 or the member 138 carried thereon when the. sound armhas been raised by its lifting mechanism, but it lies out of this pathwhen the sound arm is lowered. The member 138 is pivoted at the base ofthe T to the edge of lever 68 as shown at 138 in Figs. 18 and 19. On theunderside of the cross piece of the T is carried a downwardly extendingpin 139 which rests upon the upper surface of lever 129 so that the T-shaped member is raised or lowered about its pivot 138' according to theposition of lever 129. The stem of the T of member 138 is undercut sothat in the lowered position the cross piece of the T can drop below theupper surface of lever 68 as shown in Fig. 19.

In the raised position of lever 129 (i. e. in the position for a 10"record) the member 138 is raised to a position where it passes over thepost 131 as lever 68 moves outwards (towards the right in the drawings)and consequently the sound arm is moved outwards by contact of post 131with the edge of the lever 68 itself.

In the lower position of lever 129 (i. e. the position for a 12"diameter record) the member 138 is lowered and the cross-piece of the T(see Fig. 1) acts as a packing piece between the edge of lever 68 andpost 131 and the sound arm is moved a greater distance outwards for thesame swing of lever 68.

In the case 01 repeater operation (Figs. 4 and 5) when the lever 132 isin the position shown in full lines'in Fig. 1 and lever 129 and packingpiece 138 are raised the throw of lever 68 through the engagement of pin'70 in the slot '71 is exactly sufficient to re-position the stylus overor just outside the starting point of a. 10 record, and to repositionthe stylus over or just outside the starting point of a 12" record (Fig.4) when the lever 132 is in the position shown in dotted lines in 15Fig. 1 and lever 129 and packing piece 138 are lowered. A slight inwardmovement of the sound arm (if required) is caused by the axis ofrotation of the sound arm being at an angle to the vertical. If therepetition is to be effected of a record which in the first instance hasbeen automatically transferred from 'the magazine to the turntable thecontrol lever 74 is moved into the centre notch of catch plate 167, tosuitably adjust the path of reciprocating plate 6. The lever 132 in thiscase is already in the proper position for determining the extent ofoutward movement of the sound arm. When a record is placed manually onthe turntable and it is intended to play it repeatedly it may benecessary to adjust lever 132 by hand. During magazine operation (Figs.1 and 3) the throw of lever 68 is sufiicient, owing to the increasedlength of time that pin 70 remains in part 72 of "l-shaped slot 71 inplate 6, to move the sound arm 27 outwards whether by the end of lever68 or the member 138 engaging with post 131 until the stylus reaches aposition outside the edge of the largest records. This as previouslystated is for the purpose of aflordinga clear passage for thetransferring lever 95 and the record carried thereby from the magazineto the tumtable. After the new record has been deposited it is necessaryfor the sound arm to be moved inwards to a position where the styluswill engage the edge of the ten or twelve inch record as the case maybe, before playing can be commenced.

This inward movement is effected by means of a hook 189 pivotallymounted at 189' beneath the end of lever 68. This hook is adapted toengage post 131 only when the sound arm is in the raised position, butduring magazine operation it remains in the raised position not onlyduring its movement outwards but also during its movement inwardstowards the edge of the record. During the movement of the sound armoutwards urged by lever 68 (or member 138) the hook 1891s caused bymeans described below'to take up a position where it embraces the post131 and during the subsequent movement of lever 68 inwards the sound armis moved inwards by the pull of hook 189 upon post 131. The distancemoved inwards by the sound arm to engage the edge of a ten or a twelveinch record is determined by the moment at which the pivoted hook 189 isrocked to release post 131 and this is determined by the position of themovable lever 129 previously described. For these purposes the lever 129carries on its upp r surface a pin 140 (Figs. 18 and 19) and a pair ofstops 141 and 142 i at different positions on the lever and at suchdistances above the surface of the lever that one or other will occupy aposition to engage the hook 189 according as the lever 129 is raised orlowered. These stops 141 and 142 may be formed in one piece as shown inFigs. 18 and 19. The hook 189 is provided with an elongated end or tail143 (Figs. 3, 18 and 19), and during the outward movement of the lever68 this tail meets the pin 140 so that the hook 189 is caused to turnabout'its pivot 189 andto embrace post 131 as shown in full lines inFig. 3. During the return movement of lever 68 the sound arm is drawninwards by the hook 189 pulling upon post 131. When the tail 143 of thehook 189 contacts with one or other of the stops 141 or 142, whicheverlies in the path of said tail 143, the hook 189-is caused to swing aboutits pivot 189' on lever 68 v and the inward movement'of the sound armceases. Whether this movement ceases at a point where the stylus is overthe edge of either a 10" or a 12" record depends, as previously stated,upon whether the lever 129 carrying the stops 141 and 142 is in theraised or lowered position and this in turn depends upon the size of therecord last conveyed from the magazine is clear of the turntablespindle, whereupon thev record is slewed off by its engagement with theedge of the rotating turntable at the side opposite to the movable post.This is illustrated in Fig. 6. v

The post '76 is mounted to move vertically in a tubular bracket 77screwed to the base plate 4 by screws 77'.

The post 76 is furnished with a soft pad 78 on its upper end and itslower end rests upon the end 79. of a lever 80 mounted to rockvertically on a pin 81 carried in lugs 82 upstanding from a plate 83mounted for a reason stated below to turn horizontally about a screw 84in the base plate 4. On the end of lever 80 away from post 76 is carrieda roller 35 adapted, during magazine operation, to roll on a cam 88mounted to rotate with cam shaft 12. A spring 86 tends to push the outerend of lever 80 upwards. When, during magazine operation the roller 85reaches the depression 87 in the revolving, cam 88, the end 79 of lever80 rises under the action of spring 86 and lifts the movable part 76 sothat the record on the turntable is tilted until it is free of theturntable spindle 13, when it is slewed off by the rotation of theturntable and slides onto an inclined chute (not shown) to thecompartment 3 of the cabinet. 7

When the machine is set to operate as a repeater or as an ordinarymachine, the record removing mechanism is rendered inoperative by meansof the hand operated lever 74 referred to above, which is connectedthrough a link 91 (see Fig. 2) with the plate 83 whereby the rockinglever 80 when lever 74 is moved, is moved about the screw 84 (Fig. 6)until the roller 85 is removed from the cam 88, the lever 80 then comingto rest upon a post 92 provided for the purpose.

The means employed in the construction illustrated for furnishingrecords to. the turntable during magazine operation will nowbedescribed, but these means form the subject of my co-pendingapplication for patent Serial No. 243,713. v A pile 01' records 93 (Fig.7) which may be of the same or diflerent sizes, and without spacingmeans between them, is carried upon a fixed plate 184 supported upon anarm 185 (Fig. 1) extending from the base plate 4. A vertical spindle 94extends through the plate 184 and through the apertures in the recordsto centre them. A swinging arm '95 (Fig. 7) mounted to rotate with avertical shaft 96 carried in bearings 97, 98 on a part 99 fixed to thebase plate 4, is arranged to swing between positions in whichrespectively a downwardly extending pin 'on the arm 95 Means describedbelow are provided for mow ing the arm vertically upwards and downwards.and for swinging it horizontally from one operating position to another.

Short hooks, just long emugh to hold one disc, on the ends of springarms radiating from a boss 191 on the underside of the swinging arm 95,operate when the swinging arm 95 is brought vertically downwards on therecord pile 93 togrip and raise the uppermost record in the pile andafter the arm 95 has been swung into the position over the turntable, asshown in Fig. 3, the hooks release the record which falls on to theturntable 90. Two sets of arms 100 are provided, one to pick up 10"discs and the other 12".

The arm 95 is swung during magazine operation between the recordmagazine and the turntable by the engagement of a projection 114(Fig. 1) on the reciprocating plate 6 with the end 113 of a curved lever101, pivoted to the base plate 4 at 102 and having a curved end 103(Fig. 7) carrying a downwardly extending pin 104 which passes through anaperture 105 in a block 106 arranged to slide in a yoke 107 carried on aring 108 on the pillar 96. During magazine operation movement 01 plate 6towards the right rocks the lever 101 clockwise and the movement of thislever 101 is normally imparted to the pillar 96 to swing the arm 95between the magazine and the turntable. The connection between the ring108 and the pillar is however in the form of a spring catch, the spring110 being carried on a collar 111 pinned to the pillar 96 while its ballend 112 engages in a depression in the ring 108. Thus the-arm 95 maywhen desired he swung about its axis without moving the lever 101, forthe purpose of enabling records to be placed in or manually removed fromthe magazine.

The passage of a record from the magazine to the turntable determines,according to the size of the record, the position of the sound box whenit is lowered on to the record. This is effected as follows:

During magazine operation the position of the lever 132 and consequentlylever 129 is determined automatically by and during the passage of therecord next to be played, from the magazine to the turntable. If thelast record played was a 10" record, the arm 132 occupies the full lineposition in Fig. 1, or if a 12", the dotted position. On the recordcarrier 95 swinging to the right with the next record, the latter, evenif a 10, will strike the stud 13B, and push the roller 134 off the flat135, when the inclined surface 135 will push it to the other end to theposition shown in full lines in Fig. 1. Further movement of carrier 95towards the turntable with a 10" record has no efiect upon lever 132when in the position shown in full lines as the stud 137 on the otherend of lever 132 is out of reach of the edge of a 1 record. In this casetherefore the lever remains in the position shown in i'ull lines in Fig.1 and the lever 129 remains in the raised position.

With a 12'record however, further movement of carrier 95 towards theturntable results in lever 132 being moved into the dotted position,through the edge of the record wiping against stud 137. In this casetheretore, the lever'132 is caused to occupy the position shown indotted lines in Fig. 1 and the lever 129 its lowered position.

In order to allow time m the record transferarm is swung over theturntable a limited moveue im ment of plate 6 is permitted beforeprojection 114 contacts with the end 113 of lever 101 by provid ing aspace between the parts 114 and 113 as shown at 123 in Fig. 1. 0n theother hand the arm 95 is required to commence its return movementquickly after depositing a record on the turntable and for this purposean auxiliary lever 124 (Fig. 1) is pivoted at 102 on base plate 4., andone end of this lever is connected to lever 101 by a spring 125 whilethe other engages a surface 126 on plate 6.

During movement of plate 6 to the right the lever 124 is in contact withthe plate 6, moving away from lever 101 under the pull of spring 125until projection 114 contacts with the end 113 of lever 101 and movesthe latter. But immediately the plate fibegins its return movement thelever 124 and also lever 101, owing to "the spring connection betweenthese two, begin their return movement together with the transferringarm 95.

The underside of arm 95 carries a downwardly extending pin 127 (Figs. 7and 8) which, in the extreme positions of the arm 95, registers with'aperture 186 (Figs. 1, 8 and 8) in a part 128 forming an extension ofthe bearing 97, and the pin 127 enters one or other of said aperturesduring the rising and falling movements of the arm 95 and guides thelatter during said vertical movements.

To alter the machine to operate as a repeater the path of thereciprocating plate 6 is, as pre viously described, changed bymanipulating lever 74, and the projection 114 is raised in Fig. 1 sothat during reciprocating movement of said plate 6 it passes the end 113of lever 101.

The record transferring mechanism in this case therefore remainsinoperative.

Vertical movements are imparted to the arm 95 for the purpose ofenabling the record transferring means to engage and lift a record to aheight sufiicient to enable it to be swung horizontally over theturntable and to release the record from the transferring device toallow it to fall on to the turntable. The latter movement however, issmall as compared with the former.

. The up and down movements are imparted to the arm 95 by a lever (Fig.9) pivoted on a support 116 extending downwards from plate 1, one end ofsairl lever projecting beneath the lower end of the pillar 96 carryingthe arm 95. while the other end carries a roller 117 engag ing aninverted box cam 118 (Fig. 22) on the lower end of the cam shaft 12.sions are formed in this cam, one of which 119. permits the lever 115 tooccupy at the appropriate time the position shown in dotted lines inFig. 9 so that the arm 95 can fall by gravity the distance necessaw toenable the hooks on the spring arms 100 to grip the edge of the uppermost record in the magazine. while the other depression permits thelever 115 to take up a position such that the arm 95 is free to drop ashort distance when over the turntable. The pin 199 is capable ofsliding vertically in a sleeve 191 extending below the boss 191 on arm95. When the arm 95 is lowered, to release a record. the pin 190 strikesthe turntable spindle 13, and the pin 190 and a spider 192 rigidtherewith are raised with regard to arm 95 and the arms 100 holding therecord are spread to disengage the hooks on the arms 100 from the edgeof the record, so that the latter falls on to the turntable.

The support 116 for the arm 115 is moved in Two depresi iii Cir"

the plate 4 by the lever '74 through links 91 and 120 when the lever 74is placed in the position for repeater operation, so that then theroller 11'? on lever 115 is out of the path of the cam 118 and novertical movements are imparted to the record transfer mechanism.

That end of lever 115 carrying the roller 117 is arranged to rest uponone end of a second pivoted lever 121 (Fig. 9) the other end of whichengages beneath the lower end of the vertically movable magazine spindle.94. Thus when the arm of the transferring mechanism is in the raisedposition, and held there by the cam 118 and lever 115, the spindle 94 isrigidly held raised by the lever 121 and the placing of records on thespindle to form the magazine is facilitated. When however, the arm 95 islowered the lever 121 is free to rock and the spindle 94 to drop, whenthe pin 190 is lowered onto it, so

that the spring arms can pick up the uppermost record. Springs 122 areprovided to balance the weight of the lowering parts.

When it is desired to use the machine as an ordinary manually operatedmachine, the clutch lever 17 is held out of engagement with teeth 22, sothat the automatic mechanism acting on sound arm and magazine is notoperated. This is ef-- fected as follows: When the control lever '74 ismoved into the right hand notch in catch lever 167, it moves the plate 6to a position where its lower edge in the drawings contacts with amember 144 (Figs. 1 and 2) pivoted on the base plate 4 at 144 andnormally pulled in a counterclockwise direction by a spring 145. Themember 144 is thereby rotated about its pivot 144' against the spring145 and a projection 146 on said member 144 is moved against the end ofclutch lever 1'7 as shown in dotted lines in Fig. 2 and lever 17 isthereby prevented from moving into the clutched position even whendetent lever 24 is rocked as previously described.

To prevent manual movement of the magazine arm 95 during ordinaryrunning, a further looking device 4''! is connected with the link 120and when the control lever 74 is moved into the position just referredto, a projection on this member 147 is moved into the path of a lug 124'on lever 124 (Fig. 2) and any possibility of swinging movement on thepart of the record transferring mechanism is thereby prevented.

The machine is brought to a standstill automatically after magazineoperation when the last record has been removed from the turntable. Thisis effected by cuting oiT the currentto the motor. For this purpose thering 58 on the sound arm is provided with a forwardly projecting finger156 (Figs. 1 and 10) which operates in a manner to be described to openthe motor circuit by opening a spring switch 15'! (Figs. 1, 21 and 24)formed ofa pair of spring arms 158 and 159 normally urged together, thefree end 159' of the lower* spring 159 being bent upwards and to lieover the end of the upper spring 158. During magazine operation, whenthe magazine becomes empty the record transferring device 95 moves overthe turntable without a record in the same manner as i .whentransferring a record. When the sound arm having been swung outwards, isafterwards moved inwards from its outermost position as previouslydescribed and is lowered as when about to engage the stylus with arecord on the tumtable, the stylus drops slightly below the normal levelowing to there being no record to support it. The sound box thereuponswings inwards towards the edge of the turntable owing to theinclination operation.

of the axis of the sound arm, and as a result of the additional drop ofthe sound arm, the finger 156 rests upon the upturned end 159 of thelower switch arm 159, bends this latter down as shown in dotted lines inFig. 21, so that the contacts are moved apart and the motor circuitbroken. The motor and thereby the machine is stopped.

A stop 160 is provided against which the finger 156 abuts to limit theinward movement of the sound arm so that the stylus or sound box shallnot scrape against the edge of the turntable.

When the machine is operating as an ordinary manually operated machine,it is stopped after the playing of a record by the mechanism illustratedin Fig. 20, where a detent 151 is employed to retain the moving part 152of an electric switch in the on position during playing, by theengagement of the detentwith a stop 153' on the switch arm 153, thedetent 151 being rocked at the end of a record to allow the switch torotate and cut off record isreached, by the movement of the arm 154 ofthe clutch detent lever24, the movement of the arm 154 being transmittedto arm 151' of detent 151 through a stud 155 on extension 148 of lever74 when the latter is set for operating as an ordinary machine.

It will be clear that this automatic stopping means must not operate tostop the machine when the detent 24 is rocked during magazine 'orrepeater operation and to this end the stud 155 is so mounted on theextension 148 of lever 74 that during magazine or repeater operation thestud is removed from between lever 154 and detent 151,

as shown in full lines in Fig. 2, and movements of the former are nottransmitted to the latter. The stud is shown in dotted lines in Fig. 2in the position for operating the stopping mechanism 152. The stud 155is mounted in such a manner as to be capable of a limited movement in aslot in extension lever 148.

The means for automatically imparting movement in a counter-clockwisedirection to detent 24 comprise a ratchet wheel 28 (Fig. 10) mounted torevolve against friction on a pin 28' on arm 166 of detent 24. An arm 48extending radially from the sound arm carries a plate 26 capable ofvertical movement about a pivot 26' (Figs. 10 and 12) on arm 48 butnormally'tending to move downwards-under its own weight. This plate isprovided with teeth on its lower edge which teeth enand detent 24 isrocked. If the movement impart-1 ed to plate 26 is. greater than thehorizontal movement permitted to wheel 28, by the detent 24, the

wheel 28 will rotate against friction sufliciently to permit theadditional movement of plate 26. The pivotal connection of plate 26 witharm 48 allows for variations in the height of the sound and owing todifierences in thickness length of stylus and permits the drop below thenormal level as abo' K to operate switch 159 after completed ma azine Inorder to prevent the coiitrol. lever 74 beingmoved during thetime thatthe cycle of automatlc operations is taking place the extension 148 ofsaid lever 74 (Figs. 1 and 2) is provided with a series of notches 149into one or other of which a lug 150 on an arm 154 of detent 24 enterswhen the automatic cycle starts and remains held therein during thecycle, and is held in this position so long as the clutch is in. On theunderside of the end 23 of lever 24 is a pin 30, which, when the clutchis out rests in a recess in the inner wall of a ring 31 upstanding fromthe member 34 rigid with the cam shaft 12. When the detent 24 is rockedeither automatically or by the push rod 163 and. the clutch put in, thepin 30 is moved from within this recess 35, and since the ring 31rotates with the cam shaft 12, the recess 35 is moved from a positionopposite the pin 30, which is therefore unable to return to its previousposition until the cam shaft 12 and the ring 31 have performed acomplete revolution, corresponding to the cycle of automatic operation,and recess 35 returns to a position opposite pin 30. Lug 150 on arm 154therefore locks control lever 74 during the whole of the time that camshaft 12 is rotating and the automatic operations are being effected.

During revolution of the shaft 12, the pin 30 is guided between the ring31 and cam 88.

The movement of detent lever 24 in a counterclockwise direction underthe action of its spring 25, brings the end 23 into the way of clutchlever 17 and the tooth 21 is disengaged from the plate 15.

With a view to preventing hunting on the part of clutch lever 17 owingto its spring connection with plate 15, when the end of lever 17suddenly meets end 23 of detent 24, a spring pressed finger 36 pivotallymounted on the upper surface of wheel 16 outside ring 31, is at theappropriate time brought to a position where its free end abuts againstthe rear surface of the end 18 of arc-shaped level" 17 and the member 36thus serves as a stop to' prevent any tendency that the end 18 of lever17 may have to move away from the end 23 of detent24.

If after the machine has last been stopped by the sound arm dropping andopening switch 157, and it is desired to start the machine afresh, thisis effected after the magazine has been refilled by pressing upon knob162 at the front of the machine and rocking detent 24 as previouslydescribed to engage the clutch 21, 22. The closing of the motor circuitis automatically effected simultaneously by means of a switch 161 (Figs.1 and 2) provided in a circuit in shunt with the switch 157, so that themotor circuit can be closed independently of switch 157. This switch 161comprises a pair of spring arms which rest normally apart, beingsuitably mounted on. the base plate 4. When the detent 24 is rocked bypressing the knob 162, a downwardly extendin pin 165 of insulatingmaterial on the underside of arm 166 of detent 24 presses the springarms of switch 161 together. Thus the motor circuit is closed, the motorrotates, and the clutch being engaged the automatic cycle commences. Theswitch 161 remains closed until the pin 30 on detent 24 re-entersdepression 35 when it opens owing to the detent lever 24 rockingcounterclockwise, but in the meantime the sound arm has been moved andthe other switch 157 is closed by the rising of spring arm 159.

The automatic operations can also be initiated at any time during theplaying of a record by pressing knob 162 to rock detent 24.

In the wiring diagram Fig. 24, A and B are the points of connection ofthe motor circuit to the supply mains. C is a main switch and theswitches 152, 157 and 161 are indicated diagrammatically.

The operation of the machine is as follows: For magazine working thepile of records to be played is placed in the magazine and the mainswitch C and switch 152 are closed. Control lever 74 is moved to theposition where roller 74 engages in theleft hand notch of spring-pressedcatch lever 167. Knob 162 is pressed inwards to move rod 163longitudinally so that detent lever 24 is rocked about its pivotwhereupon the clutch lever 17 is permitted to take up the clutchedposition and at the same time the motor circuit is closed through switch161. The cam shaft 12 rotates and the plate 6 is moved to the rightthrough the action of cam 11 upon ring 9 connected to said plate. Thelever 44 is rocked about its pivots in studs 45, by engagement of roller43 on said lever with member 41, to raise the sound arm and sound boxabout the axis 49. The lever 68 is swung outwards by the engagement ofpin 70 in slot 71 to push the sound arm outwards to the fullest extentand the record ejecting post '78 is lifted but at the commencement ofoperations of course there is no played record on the turntable to beejected.

The record transferring device 95 engaged with the uppermost record inthe magazine, is first raised by box cam 118 and lever 115 and thenswung over from the magazine to a position over the turntable, by theengagement of projection 114 on plate 6 with the end 113 of lever 101,and when this position is reached the record is allowed to fall on tothe turntable. The lever 132 is set in the course of this transferringmovement as described above, according to the size of the recordtransferred from magazine to turntable. After the record has beendeposited the return movement of plate 6 commences. Transferring device95 now swings back over the magazine and drops down to the extentnecessary to engage the hooks on levers 100 with the now uppermostrecord in the magazine. At the same time return movement of lever 68 iseffected and the sound arm is drawn inwards by engagement of the hook189 with post 131, to a point where the stylus is over the edge ofwhatever size record is on the turntable, at which point post 131 isreleased by hook 189 through the engagement of tail 143 of the hook withone or other of stops 141 or 142. The sound arm is then lowered intoengagement with the record through the lowering of lever 44 and playingcommences.

The plate 6 moves towards the left until the cam shaft 12 comes to restthrough the engagement of pin 30 in depression 35 and the removal oftooth 21 on lever 17 from toothed wheel 22 by the contacting of end 18of lever 17 with the end 23 of detent 24.

The stylus moves in across the record and when the end is reached areversal of direction of movement of the sound arm is imparted forexample by an eccentric groove as stated above. Thereupon the detent 24is again rocked this time by the engagement of ratchet 26 with ratchetwheel 28 and the clutch is again thrown in and the cycle of automaticoperations is repeated. This process may be repeated as long as anyrecordsremain to be fed from the magazine. If during magazine operationit is desired to play a particular record over again one or more timesinstead of passing on to the next record, control lever 74 is -moveduntil roller 74 engages in the centre notch of catch lever 167. Thisresults in a modification of 1,968,927 the position and subsequent pathof travel of plate 6, and also the removal of the record ejecting post76 from the influence of cam 32 through link 91 and pivoted plate 83.

In this-new position of plate 6 the projection 114 is caused to pass'theend 113 of lever 101 when the plate 6 moves and the record transferringmeans therefore remains inoperative. The sound arm, raised by lever 44as before, is moved outwards by lever 68 but only so far as is necessaryto bring the stylus to a position over the commencement of the record tobe replayed whereupon it is lowered directly until the stylus contactswith the commencement of the record to be replayed. The sound armremains unaffected by the return movement of the plate 6 towards theleft owing to the automatic deflection of member 41 by plunger 62. Inthis case the record having been fed originallyfrom the magazine thelever 132 is already set to correctly position the packing piece 138 togive the correct extent of outward movement of the sound arm. If howeverthe record to be repeated is placed on the turntable manually it may benecessary to set the lever 132 by hand to the correct position accordingto the size of the record to be repeated.

During magazine operation when the magazine is emptied the machine isstopped by the opening of switch 157 through the sound arm dropping to alevel below that which it occupies when playing. If however the machineis required to stop at the end of any particular record, the controllever 74 may be moved during playing to the position where roller 74' isengaged in the right hand notch in the catch lever 167. In this positionthe clutch is held against moving in when the detent 24 is rocked bymember 146, so that none of the automatic cycle of magazine or repeateroperations takes place. The movement of lever 74 into this positionintroduces stud 155 between part 154 of detent 24 and detent 151, andthe rocking movement of detent 24 when the end of a record is reached isimparted to member 151 and the switch 152 is thereby opened to stop themotor.
